The optical servo system for a tape drive that functions to align a read/write head with the data tracks written on a recording surface of a tape by reading optical servo tracks that are formed on the back side of the tape. This process decouples the magnetic recording of data on the recording surface of the tape from the optical servo system which makes use of servo tracks formed on the back side of the tape. The data storage capacity of the tape is increased since the entire recording surface of the tape is filled with data tracks and the precise alignment of the read/write head makes it possible to place the data tracks closer together. Regions of contrasting reflectivity or phase are also provided on a surface of the read/write head to enable the optical servo system to view an image of both the read/write head and the entire back side of the tape to thereby align the movable read/write head with the data tracks.
A method of aligning a head with a storage media, comprising the steps of:
A system for aligning a head with at least one of a plurality of data tracks written on a first side of a data storage media as said media passes over said head, wherein said media also includes optical servo features formed on a second side of said media, said system comprising:
In a tape drive, a system for aligning a read/write head, that is moveably attached to said tape drive, with a selected set of a plurality of data tracks written on a first side of a tape as said tape passes over said read/write head, wherein said tape also includes optical servo features formed on a second side of said tape, said system comprising:
A tape library comprising a plurality of tape drives, at least a portion of said tape drives comprising:
In a tape library comprising a plurality of tape drives, at least a portion of said tape drives operable for aligning a head with a storage media and comprising the steps of:
